Detailed Description

The following describes the embodiments of the present invention in detail. It is to be understood that the description of the embodiments herein is for purposes of illustration and explanation only and is not intended to limit the invention.

In the present invention, the use of the terms of orientation such as "upper and lower" in the case where no description is made to the contrary generally means the orientation in the assembled and used state. "inner and outer" refer to the inner and outer contours of the respective component itself.

The utility model discloses a first aspect provides a car ventilation cushion, as shown in fig. 1 and 2, car ventilation cushion is including filling up body 10, be provided with the ventilation passageway in filling up body 10, be provided with a plurality of vents 50 with external intercommunication on the ventilation passageway.

The shape of the cushion body 10 may be various, and may be a square, a rectangular parallelepiped, an oval, or the like.

In an alternative embodiment, the air duct includes a main air duct 21, and the main air duct 21 is spirally distributed inside the cushion body 10 with reference to the shape of a snail shell, or the main air duct 21 is distributed inside the cushion body 10 in a zigzag line folded in half. Of course, there are many other distribution modes of the main air duct 21, and the common of these distribution modes is: the path of the main air passage 21 passes through the corners of the inside of the mat body 10 as much as possible, or the main air passage 21 occupies the inner space of the mat body 10 as much as possible.

In another alternative embodiment, as shown in fig. 3 to 6, the ventilation passage includes a main ventilation passage 21 and a branch ventilation passage 22 communicating with the main ventilation passage 21. The main air duct 21 penetrates from the front end of the cushion body 10 to the rear end of the cushion body 10; the branch air tunnels 22 extend from the main air tunnel 21 to both left and right ends of the mat body 10.

Preferably, the ventilation openings 50 communicate with the branch air ducts 22, that is, the ventilation openings 50 are not provided on the side walls of the main air duct 21. Further preferably, the ventilation openings 50 are distributed along the path array of the branch ventilation ducts 22.

In order to prevent air discharged from the vent 50 from being blocked by a passenger as much as possible, thereby reducing a ventilation effect. A first protrusion 30 is hermetically connected to the ventilation opening 50, and the first protrusion 30 is hollow inside and communicates with the branch ventilation channel 22.
